IMPROVEMENT lN FURNACE-GRATES.

Specification forming part of Letters Patent No. 126,060, dated April23, 1872.

SPECIFICATION.

To all whom it may concern:

Be it known that I, CHARLES KUGLER, of Barnesville, in the county ofBelmont and State of Ohio, have invented certain new and usefulImprovements in Grate-Bars and Attachments thereto; and I do herebydeclare that the following is afull, clear, and exact descriptionthereof, reference being had to the accompanying drawing and to theletters of reference marked thereon, which form a part of thisspecification.

My invention is intended as an improvement upon the grate-bar for whichJohn W. Stanton has made application for Letters Patent; and itconsists, first, in the construction of the bearing-bar, and, second, inthe construction of the separate grate-bars, all of which will behereinafter more fully set forth.

In order to enable others skilled in the art to which myiuventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation referring to the annexed drawing, in which-Figure 1 represents a front View. Figs. 2 and 3 represent the ditferentforms of grateba-rs. Fig. 4 is a side view of the pieces in which thebearing-bars have their support; and Fig. 5 a plan of the grate-bar 'incouples.

A represents the bearing-bar, provided with V-shaped pivots a a, placedin suitable bearings so as to allow it to oscillate freely. Thisoscillating bearing-bar is constructed so as to form a series of cranks,b b, the object of which is to support the grate-bars B and O. Eaclr"end of the grate-bar B has a semicircular box, d, to rest upon thecranks b, while the grate-bars (l have at their ends downwardprojectingarms 6, with similar boxes d at their ends to rest upon the cranks b ofthe oscillating bearing-bar, and so on alternating until saidbearing-bar is filled with grate-bars forming a complete set of furnacegrate-bars, which will all be on a level whenthe bearingbars hang intheir normal positions.

The object of the oscillating bearing-bar is to produce compoundmovement of the gratebars in a vertical and longitudinal direction bymeans of the lever D attached to the same, and to relieve the grate-barsfrom friction, which necessarily occurs when the ends rest upon astationary bed-plate.

The grate-bars B and G are each formed by uniting two parallel sectionssecured together by rivets or bolts at it. On the inside of each of suchsections are projections ff, for the purpose of forming a centralair-course parallel with the bar. The objects of forming each bar intotwo parallel sections are for convenience of molding the bars and forgiving considerable more air-courses and surface without additionalweight.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

The grate-bars fastened or secured together in couples, combined withthe bearingbars, and arranged to operate substantially as hereindescribed.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

CHARLES KUGLER.
